Question

我想为API创建一个Stub，并希望验证服务器返回的API调用和响应。为此，我实施了WireMock示例：

import org.junit.Rule;
import org.junit.Test;

import com.github.tomakehurst.wiremock.junit.WireMockRule;

public class MockTestDemo {

    private static final int WIREMOCK_PORT = 8080;

    @Rule
    public WireMockRule wireMockRule = new WireMockRule(WIREMOCK_PORT);

    @Test
    public void exampleTest() {

    stubFor(get(urlEqualTo("/login")).withHeader("Accept", equalTo("application/json"))
            .willReturn(aResponse().withStatus(200).withBody("Login Success")
                    .withStatusMessage("Everything was just fine!"))
            .willReturn(okJson("{ \"message\": \"Hello\" }")));

       verify(getRequestedFor(urlPathEqualTo("http://localhost:8080/login")) 
            .withHeader("Content-Type",equalTo("application/json")));       }

}

但是低于错误：

com.github.tomakehurst.wiremock.client.VerificationException: Expected at least one request matching: {
  "urlPath" : "localhosturl/login",

   "method" : "GET",

  "headers" : {
    "Content-Type" : {
      "equalTo" : "application/json"
    }
  }
}

如果我评论验证部件然后测试执行成功，我也通过调用http://localhost:8080/login使用邮递员验证了相同的并且它成功返回响应？

我在这里缺少什么东西？

Answer 1

在您的代码中，您正在查找响应，然后验证是否已为该存根发出请求。但是，您没有调用端点，因此测试失败。

您需要在验证端点之前调用端点。

如果您使用Apache Commons HttpClient，您可以将测试编写为：

@Test
public void exampleTest() throws Exception {

    stubFor(get(urlEqualTo("/login")).withHeader("Accept", equalTo("application/json"))
            .willReturn(aResponse().withStatus(200).withBody("Login Success")
                    .withStatusMessage("Everything was just fine!"))
            .willReturn(okJson("{ \"message\": \"Hello\" }")));

    String url = "http://localhost:8080/login";
    HttpClient client = HttpClientBuilder.create().build();
    HttpGet request = new HttpGet(url);
    request.addHeader("Content-Type", "application/json");
    request.addHeader("Accept", "application/json");
    HttpResponse response = client.execute(request);

    verify(getRequestedFor(urlPathEqualTo("/login"))
            .withHeader("Content-Type", equalTo("application/json")));
}

com.github.tomakehurst.wiremock.client.VerificationException：预计至少有一个请求匹配
